Life Leech and Mana Leech aren't anything special, especially since they nerfed the [censored] out of them awhile back. Even 100% Life Leech on the Breath of the Dead is a joke. Life Leech barely leeches back anything now. Mana Leech is only useful if you're doing upwards of 80+ damage a shot, which can be done in PvM, but not PvP. Even with High Mana Leech % on a Ornate Axe, it can barely leech back enough Mana to cover the cost of a 4 Mana Lightning Strike in PvP.
Bladeweave is a waste of Mana in my opinion, too many broken or useless specials it can do. Block is broken, Double Strike is Broken, Feint makes you take 1/2 damage for 4 secs, can be useful, does Bleed/AI/Mortal alot less often than the broken specials. If i wanted to do one of them specials, i'd switch to a weapon that could do it.
This was crafted with a Valorite Runic Hammer before the new changes to their properties. Is Two-Handed, so good for Samurais. The Lightning is useful, especially with a Double Strike after i Disarm someone, the Stam Leech keeps my Stam up (Only dependable Leech nowadays IMO), enough SSI to make me swing fast, and 40% Dam Inc.
What's the difference between a Lightning Strike Critical or a Bladeweave AI? Both have a chance to go off, but Critical also gives +50% HCI and costs alot less Mana, and it's Mana use doesn't double if chained. The Mortal Strike is useful for when i wan't to keep someone from healing by bandies/spells/pots.
But yeah, i'd prefer to have HLA on my Wep than HLD, since HLD can be gotten from Mace & Shield Glasses, and it doesn't stack with the HLD of a wep like you'd think it would.
